'pagination_records' => 10,
'user_type' => ['User', 'Admin'],
]
?>

You can easily get value using config() helper. you can see bellow example:
routes/web.php
Route::get('get-user-type', function()
{
dd(config('global.user_type'));
});
Route::get('get-user-type', function()
{
dd(config('global.pagination_records'));
});
